URL: https://github.com/apache/mynewt-mcumgr/issues/95


   Hi, 
   
   Our devices are getting randomly bricked by updating firmware through mcumgr 
in Zephyr. It happens on both the nRF91 and nRF52 chips when we run the latest 
nRF Connect SDK 1.3. The reason is that firmware in Slot 1 is sometimes set 
Permanent flag, but we don't know how and why. When this happens, it cannot be 
erased/confirmed/reflashed/anything else. Any ideas what could be the cause and 
how to fix it?
